Facebook Workplace vs IBM Connections

Facebook Workplace
Facebook Workplace is business alternative to Facebook. Connect everyone in your company and turn ideas into action. Through group discussion, a personalised News Feed, and voice and video calling, work together and get more done. Workplace is an ad-free space, separate from your personal Facebook account.
IBM Connections
IBM Connections is social software for business that lets you access everyone in your professional network, including your colleagues, customers, and partners. Unlike alternatives IBM Connections plays well with other IBM software.

2016 - Facebook Workplace will open app store to compete with Slack to challenge IBM Connections

One of the success secrets of the super-popular collaboration service Slack is its ability to easily integrate third-party business apps. For example, it lets your team quickly discuss the new deal pulled from CRM system or process the new ticket that came from Helpdesk or add to discussion a customer that is using Skype. Facebook has found out this secret and now wants to replicate it in its new enterprise social network Workplace. For this they are launching a platform for developers that enables easy integration with other apps. Then these integrations will appear in the Workplace app store. For now the network features integration with Google's G Suite, Microsoft's cloud Active Directory and with single sign-on services Okta and OneLogin.
